1、如果需要获取面要素根据邻接关系转换成多线,使用Polygon To Line工具,需要注意的是先排除一下面要素类可能存在的重叠问题,再进行转换。 2、如果需要获取面要素完全转换成单个线要素,使用上述的第3种实现方式,即Polygon Copy To Polyline,借助这种操作可以变相使用线要素类的自相交拓扑检查面要素的自相交。 3、如果...
you can create polygons from the closed polylines that are found by the tool. The tool converts the closed polylines features that have been recorded in the Reviewer table to polygons based on the template selected. This allows the LandCover features to create a continuous base with no...
Implementation 3—Polygon Copy To Polyline 这是⼀种简单⽣硬的操作⽅式。新建⼀个线要素类（注意空间参考与⾯要素类⼀致），将要转线的⾯要素类在编辑状态选中所有要素图斑，复制→粘贴到这个新建的要素类，博主这⾥该要素类的名字是“Polygon2Polyline”。同样，我们看⼀下它的特征（请忽略图中的...
To create new geometries from existing features, you may need to create polygons based on lines calculated by other functions. The Convert Polylines To Polygon tool allows you to do this using selected lines without deleting the original line features.Start ArcMap....

ArcMap中如何将大量坐标点(point)按顺序连接成线(polyline)、生成面(polygon)[转] 工作过程中,如果获得了一批点坐标信息(如通过GPS获得的点位坐标),如何将这些坐标信息直接转换成Arcmap下面的点呢?或者说就是把这些点坐标直接转换成线或面呢?需要用到Add XY Data…工具,下面是具体的方法: 1,将数据导入到Excel里...
(4).将Polyline线转换为Polygon面 1。打开ArcMap用Add Data加载shp Polyline线文件。2。选Editor编辑\Start Editing开始编辑。3。选Editor编辑\More Editing Tools\Topology拓扑 4。在Topology拓扑工具栏中选Map Topology 再在Shp文件上打勾Ok 5。用Select Features 选择指针把线全部选中，这时Topology拓扑...
